Cement particle boards are a composite material consisting of a matrix and special binding additives. This structure allows you to combine positive traits bases and fillers, reduces deficiencies, expands the scope of application.
Specifications
DSP are wide flat slabs with a uniform structure, usually gray-brown in color. The base, making up 65%, is high-quality Portland cement with the addition of gypsum and plasticizers. Second component - wood shavings in a volume of 24%. About 8% is water. Approximately 2.5% consists of binders and hydration additives that neutralize the effect of wood extracts and regulate moisture. These can be aluminum salts, calcium salts, liquid glass. Carcinogens, harmful chemical impurities - formaldehyde, asbestos chips, etc. - are not used. That's why the material does not emit toxic fumes and is safe for health.
Technical characteristics of the DSP comply with GOST:
- specific density - 1100–1400 kg/m3;
- humidity - no more than 12%, standard value - 9%;
- maximum water absorption in 24 hours - no more than 16%;
- thermal conductivity coefficient - 0.26 W/m K;
- vapor permeability - about 0.03 mg/m·h·Pa;
- flammability class - G1;
- bending strength - 9–12 MPa, compressive strength - 0.4 MPa.
The thickness of the canvas is 4–40 mm, width - 1200 or 1250 mm, length - 2700 or 3200 mm. In thickness deviations from established standards are not allowed, a discrepancy of 1.5 mm in width and length is possible.
The surface of the sheets can be rough or smooth, depending on the degree of grinding. Finishing facade materials decorated and painted to resemble tiles, a natural stone or brick.
The weight of 1 m² of 8 mm thick canvas is about 10.5 kg.
Cement particle boards tolerate temperature changes, have good moisture and bioresistance: they are not affected by fungus, do not rot, do not swell, and do not deform. The fine-porous structure of the DSP does not interfere with air exchange and does not disturb the microclimate in the premises. Despite the presence of natural wood, the material is practically not subject to combustion.
The service life of the DSP is on average 35–40 years. In the absence of aggressive atmospheric or chemical influences - up to half a century.
Production Features
There are several technological stages:
- A mixture of water and binding additives is prepared in a special container.
- Crushed wood shavings are added to the liquid ingredients. Mineralization occurs.
- Cement is added to the mixture.
- The solution is distributed into molds, and a certain thickness is set using presses.
- They are thermally treated and the condition of the material is recorded in chambers.
- The CSM is dried, polished, and cut in accordance with established standards.
Features of installation and finishing
Cement-bonded bonding materials are intended for dry installation. In construction and finishing works they perform the same functions as chipboard, plywood, plasterboard, slate, and concrete plaster.
Some use cases:
- construction of permanent formwork during the construction of buildings, including multi-storey buildings;
- finishing, restoration of facades, foundations;
- basis for fencing, protective structures;
- arrangement of garden paths;
- Creation ceiling coverings, interior partitions, foundations for roofs, floors;
- insulation, lining of fireplaces, stoves, chimneys.
Cement particle boards are used in many types of construction and repair work. They cut perfectly, do not crumble when drilling holes for fasteners, and hold plaster and primer mixtures, paint, ceramic tiles, and wallpaper. This is an excellent base for creating various designs, interiors.
When using DSP, the main attention must be paid to storage and transportation. The material contains cement and mineral additives, so it is quite fragile and can be damaged as a result of improper loads. Before use, sheets must be in a horizontal position and supported. When transporting, the material must be placed on its edge.
During installation, the sheets are fixed to the surface at least at three points. For vertical installation use material with a thickness of about 15–20 mm. Holes for fasteners are drilled in advance. When moving slabs from place to place, precautions must be taken. When sawing, tools with working surfaces of increased hardness are used.
Putty is not used for sealing joint joints.. Cement particle board mainly consists of natural components, so during operation it can expand and contract. Visually, these changes are invisible, but rigid fixation can cause disruption of the integrity of the seams and the appearance of cracks in them. Usually the gaps between the sheets are masked silicone sealants, sewn up with narrow wooden slats and a metal profile.
The surface formed by cement particle boards is strong, stable, does not require additional leveling, difficult finishing. There is no need to soak in antiseptics or smooth out defects. The material can be coated on top with a primer to increase adhesion. Then paint or paste over it. DSP is an excellent basis for carpet, linoleum, laminate, mosaic tiles, other finishing materials.
Varieties
Classification of DSP:
- Arbolite. Universal, homogeneous, contain fine chips. Refer to lightweight concrete, are used for cladding facades, formwork, erecting partitions, creating a base for floors. There are decorative types, embossed, painted to resemble stone or brick, which do not require additional coating.
- Xylolitic. These are high-strength boards with high level thermal insulation. They are used to cover floors. Wood shavings are quite large and are located in layers in the inner part of the canvas.
- Fibrolite. In the process of their production, long softwood chip fibers are used, containing minimal amount sucrose and other agents affecting cement organic matter. The slabs have a softer texture and high sound insulation. Fibrolite is suitable for interior work: installation, wall insulation, construction of the base for ceilings.
Outdoor use
For the construction of formwork, facades, and fences, materials with maximum moisture resistance are chosen. DSPs are best suited for creating strip foundations.
Slab thickness for external works- 12–40 mm. Life time ready-made structures depends on weather conditions: amount of precipitation, difference in seasonal temperatures. On average it is about 15 years.
For external work, it is optimal to choose materials with additional protective layer made of moisture-resistant polystyrene foam, stone chips.
Before installing the formwork for the foundation, crushed stone is laid on the ground, then a layer of waterproofing. A footing is poured on top, structural pins and drainage are installed.
When installing slabs, use tin ties, fasten them at the top and bottom of each sheet, at the corners and in the middle. This provides additional stability to the structure. The distance between the rows of lintels should be about 40 cm. All wood blanks are immediately removed after the concrete has hardened.
The seams are sealed with cement mortar.
To lift and secure the slabs at the required height, winches and stable scaffolding are required.
Formwork made from DSP is installed several times faster than from wood and other materials, and the results are much better.
Interior finishing and flooring
For interior work, sheets with a thickness of 4 mm or more are used. Slabs from 8 mm are suitable for rough and finishing installation of floors. It should be taken into account that the thermal insulation and noise-absorbing qualities of thicker sheets are higher.
Tools required for work:
- saws or hacksaws;
- spatulas;
- self-tapping screws;
- screwdriver;
- building level;
- tamping roller or picking blade;
- crushed stone, mastic, primer.
When installing slab floors, the base is pre-prepared. To do this, it is leveled and a layer of crushed stone is poured. If the subfloor is made of concrete, a substrate is laid on it or support joists are installed. Thermal insulation is placed in all existing voids. Bulk materials are preferable because they do not require cutting.
The slabs are mounted end-to-end, trying not to leave gaps or cracks. The seams are treated with sealant. If materials with low moisture resistance are used, an additional layer of waterproofing is laid underneath them. Then the finishing coat is applied.
Advantages and disadvantages of DSP
Cement-bonded particle board materials have the positive qualities of natural wood and stone. They:
- durable;
- resistant to adverse conditions, high and low temperatures;
- are not deformed;
- environmentally friendly, safe for health;
- absorb noise well;
- retain heat;
- not damaged by fungus, insects, rodents;
- durable;
- can be used in conditions of high humidity.
DSP production technologies make it possible to produce sheets with specified characteristics. This significantly reduces the time and costs of work. Practicality and versatility make CBPB a sought-after building material. With their help, you can quickly erect building frames and perform any types of finishing. The composite has versatile functions and eliminates the need for additional surface treatment. This allows you to significantly save money during construction and repairs.
TO significant shortcomings Cement particle boards include:
- big specific gravity. A standard sheet has a mass of 70 kg. This makes installation difficult. It is impossible to move the slabs alone. The heaviness of the material creates a high additional load on the supporting structures;
- DSPs are not plastic and are quite brittle. They cannot be bent when strong blows easy to damage, break;
- during manual and mechanical processing, the material releases a large number of dust, so it is necessary to use special means protection for respiratory organs and eyes. After interior decoration Thorough cleaning of the premises is required.
If all rules for storing and installing the material are followed, the disadvantages are completely offset by the existing advantages.
Material cost
The final price depends on the size, quantity of materials purchased, and manufacturer.
Retail cost of one slab made in Russia, with thickness:
- 8–10 mm - 900–1100 rub.;
- 16–20 mm - 1600–1950 rub.;
- over 20 mm - from 2000 rub.
Similar materials made in China are much cheaper, but do not have the necessary technical certification or quality assurance.
DSP plate, specifications which will be presented in the article, is used quite often today. It is distinguished by outstanding qualities that have made the material widespread in private and professional construction.
Characteristics of DSP slabs
Due to the fact that the described material has excellent characteristics, it has found its wide distribution in various fields of construction. Cement particle board contains wood shavings, Portland cement, and special additives, the latter of which can provide excellent protective qualities. During the production process, all of the listed components are combined and then mixed until a homogeneous mass is obtained. Then the composition is pressed.
Products are manufactured in accordance with GOST, which strictly regulate the composition. Thus, the components should include 65% Portland cement, 24% wood chips, 8.5% water, and 2.5% impurities. Density is ensured by the presence of Portland cement in the composition, the same component guarantees the durability of the material. The production of slabs is carried out on special equipment in a factory environment, as evidenced by a quality certificate, as well as a product passport. The boards contain natural wood, which ensures the environmental friendliness of the material. This indicates that the stove is completely harmless to humans.
Positive features of DSP
The DSP board, the technical characteristics of which must be found out before purchasing, has excellent quality, which allows the use of this material in professional construction. Technological processes The manufacture of plates is based on the mineralization and bonding of all components, so the appearance of a radioactive background, the release of steam, dirt or dust can be completely eliminated.
DSP boards are actively used in the construction of strong and warm housing. Quite often this material is compared with others. The slabs described are so durable that they win in this comparison. Their service life is much longer.
Additional advantages include excellent resistance to temperature changes and frost, which meets the requirements for modern building materials.
The DSP board, the technical characteristics of which are described in the article, has proven itself to be excellent. These products do an excellent job of repelling rodents, insects, as well as mold and mildew. The material does not contain phenol, asbestos, impurities or formaldehyde resins. These slabs can be used for all types of finishes. The surface of the slabs can be plastered, finished with plastic, painted, tiled, covered with various decorative materials etc. It is easy to use this material, as it is easy to process. It contains a large amount of shavings, this makes the product look like natural wood, but these plates have high strength. You can use DSP for the construction of partitions, which will have excellent sound insulation qualities. DSP walls will be able to provide sound absorption of up to 30 dB.
Strength characteristics of CBPB
DSP, whose technical characteristics differ from other alternative materials, have a high density. This is due to the fact that the chip pressing method is used during the production process. In inner layers products contain fibers that have a longer length. This guarantees the material excellent elasticity, smoothness, and high strength characteristics. The material has several layers, so it is able to combat moisture. The special technology used in production does not allow the product to delaminate. The slab will not break, even if it is subjected to mechanical force such as bending. The material copes well with high loads; during operation, it can be subject to mechanical impacts, which makes such slabs so widespread and popular in construction.
Cost of DSP
DSP is a slab, technical characteristics, the price of which should interest you if you plan to use this material in construction, may have different sizes. The most traditional dimensions are 1250x2700 mm. the cost of such a sheet will be 675 rubles. This cost can be called very affordable, which makes this material so popular among analogues. Despite the fact that the cost of the stove is quite low, its quality remains excellent.
Dimensions of DSP
The CBPB board, the technical characteristics of which must be indicated in the quality passport, must be examined by the consumer before purchase. It is important to take into account the size range of these products. The slab can have a width of 1250 mm or 1200 mm. The latter standard is considered modern. But despite this, slabs are still produced different sizes. The length can be equal to 2700 mm, while the thickness is equivalent to 8 mm. This product weighs 36 kg. If the thickness is increased to 10 mm, the weight will be 46 kg. A thickness of 12 mm increases the weight to 50 kg, and a thickness of 16 mm increases the weight to 74 kg. A plate thickness of 18 mm makes the mass equal to 81 kg.
With a slab length of 3200 mm, the thickness can be 8 mm, while the weight of the slab is 43 kg; with a thickness of 10 mm the weight will be 54 kg, while a thickness of 12 mm gives a weight of 65 kg.
The standard size is 1200 mm. A slab with a length of 2700 mm can have a thickness of 8 mm and a weight of 35 kg. A slab thickness of 10 mm gives a mass of 44 kg. Among other things, the buyer can purchase a slab that has been manufactured to specific dimensions. The length of the slab can be 3600 mm or 3000 mm. You should not look for products on sale whose edges have a semicircular shape, since such slabs are not produced. Also, products with thinner edges are not produced in a factory. Once the slab has been purchased, it will not need to be treated with an antiseptic, since the products are antiseptic at the factory.
Scope of application of DSP
The DSP board, the technical characteristics of which must be studied before making a purchase, is used today in housing construction. The products are able to provide internal protection from the cold. This material can be used when covering walls made of concrete. The products are used in low-rise construction, as well as in the construction of special-purpose buildings. DSP is excellent for rooms where conditions are characterized by high levels of humidity. After the slab is installed, its surface does not need to be treated. It will only be enough to coat the surface with a primer or a composition that has water-repellent characteristics. Buildings that use DSP can withstand severe operational loads.
Additional product applications
The DSP board, the technical characteristics of which can be found in this article, is also used for permanent formwork equipment, which makes it possible to achieve excellent results. At the same time, some positive features can be highlighted, among them: reduction of the duration of the construction work, reducing the cost of construction, as well as ensuring the reliability and strength of the future structure. The DSP board, the technical characteristics, the use of which made the products popular, is also used today in the manufacture of window sills. Moreover, the latter are not only durable, but also quite inexpensive compared to analogues. You should not assume that due to the insignificant cost of the DSP, the window sill will have a very unsightly and unpresentable appearance. Such products have excellent decorative qualities and resemble expensive window sills made of noble materials.
Construction materials are constantly replenished with new products, or old ones are modified, becoming owners of higher technical and operational characteristics. In this article we will talk about one unique building material - cement bonded particle board. So, what is a DSP board: dimensions and price, characteristics and scope of application.
This material is made from two main components: shavings with the addition of liquid glass and other chemical additives. The photo below shows the proportions in which all the ingredients are used.
The production technology of CBPB is very similar to the production of boards. Here is the sequence of operations:
- The shavings are mixed with liquid glass and other chemical additives.
- Cement and water are added.
- The slabs are formed under a press pressure of 2−6 MPa.
- Heat treatment is carried out.
- The ends and sides of the slabs are treated with protective substances.
- For 14 days, the products are stored at a certain temperature and humidity until the binder components are completely dry and polymerize.
Attention! All factory-produced CBPB boards must comply with GOST 26816-86 and be certified.
Technical characteristics of CBPB boards and their application
The technical characteristics of this building material, like all others, determine its quality condition. Therefore, the table contains all the main parameters that affect the service life of the slab and its ability to withstand certain loads under operating conditions.

The ratio of the dimensions of the CBPB sheets: length, width and thickness with the weight of the slabs and their price
Now let's move on to the analysis of dimensional indicators. DSP is available in standard sizes:
- 2700×1250 mm;
- 3000×1250 mm;
- 3200×1250 mm.
Depending on the thickness of the panel, the volume of the material and its weight change. Both indicators are important to consider when transporting and calculating the load on the load-bearing structures of the building in which the CBPB boards will be used. Let's consider how the two indicators change depending on the thickness. The table will indicate panels with dimensions of 3000x1250 mm.

| 26 | 142,2 | 0,104 |
At what prices can you buy cement bonded particle board?
Depending on the dimensional parameters, the price of the products also changes.
csp plate
It should be noted that the price of CBPB boards of the same thickness differs slightly, for example, 16 mm. The difference is only 50 rubles. But if the volume of material used is large, then the difference will be considerable.
Attention! Dimensional parameters: length and width when ordering by individual projects can be adjusted during the production process to the required parameters. The thickness remains unchanged within the limits established by GOST.
Where are CBPB boards used?
The scope of application of cement bonded particle boards is quite wide:
- : regular and ventilated;
- : floor, ceiling, walls;
- construction;
- as permanent formwork for pouring various building structures;
- during construction.
Advantages and disadvantages
Let's start with positive aspects material:
Now the disadvantages:
- The weight of the DSP boards is decent; even a small sheet of 10 mm thickness weighs more than 50 kg. It is beyond the power of one person to lift it and install it where required. And lifting material to the upper floors will require the use of lifting equipment, which increases the cost of the work performed.
- If DSP panels are used outdoors, their service life is reduced to 15 years.
Processing rules - what you can use to saw and drill CBPB boards
Whatever one may say, CSP is a concrete stone filled with shavings (wood filler). Therefore, when the question is raised about how to process the material of this type, cannot be mentioned hand tool. Cutting and drilling can only be carried out with electric tools.
So, we considered the topic of CBPB boards. This is actually an interesting building material, which has recently been gaining popularity, especially among residents northern regions. If you have any questions about installation technology, prices and types, we are ready to answer them. Write in the comments, and our editors will definitely answer.
Cement particle boards
Cement bonded particle boards (CBPB, cement bonded particle board) are a building material with unique properties, used in “dry installation” technology. DSPs belong to a generation of modern composite building materials that have properties that combine the strength and durability of cement with the flexibility and ease of wood processing. The universal technical characteristics of DSPs have already been fully appreciated all over the world.
Due to their high technical and quality characteristics, the slabs have a wide range of applications and can facilitate the solution of a number of problems arising during construction and repair work, in interior and architectural projects. The use of cement particle boards can significantly reduce not only material and time costs for any construction and repair work, but also optimize the operating costs of the finished building due to the durability, heat-insulating properties and other useful qualities of cement particle boards.
Cement particle board is used with equal success both on large construction projects and in the construction of dachas and cottages.
Cement and wood are two fundamental materials that have been used in construction throughout human history. For a long time These materials were used separately, and only in the early 20s of the last century did research begin in the field of the physicochemical relationship between cement and wood. At the end of the 20s of the 20th century, cement was already widely mixed with wood shavings, and in the early 1940s. people learned to form slabs from a cement-bonded mixture. In 1940, the first fiberboards were produced, consisting of a compressed mixture of cement and long wood fibers. Subsequently, boards made from shorter fibers were produced, which became the prototypes of modern cement-bonded particle boards.
The slabs are made by pressing a molded technological mixture consisting of softwood chips, Portland cement, minerals and water.
ABOUT The main properties of cement bonded particle boards are:
- environmental and hygienic safety - do not contain formaldehyde resins, phenol, asbestos and other toxic and harmful substances;
- resistance to rotting, not affected by fungus and mold, resist the effects of termites, insects and rodents;
- resistance to gasoline, oils, urea, solutions of acids and alkalis, solutions of disinfectants;
- durability (guaranteed service life in building structures is at least 50 years);
- high strength and wear resistance;
- good sound insulation and thermal properties;
- workability similar to wood with higher strength;
- fire resistance and fire safety: flammability group: G1 (low-flammable), flammability group: B1 (low-flammable), flame propagation group: RP1 (non-propagating), smoke-generating ability group: D1 (low-smoke-generating), toxicity group of combustion products: T1 (low-hazardous);
- resistance to atmospheric influences: thickness swelling of CBPB over 24 hours is no more than 2%, water absorption over 24 hours is no more than 16%;
- suitability for use both inside and outside residential and commercial premises;
- variety of surface finishes: painting, plaster, cladding ceramic tiles, paneling with wood, plastic, etc.;
- Suitable for use in all climatic regions.
The quality of the slab is ensured by strict quality control by a certified factory laboratory in accordance with GOST 26816-86 and the European standard EN 634.

Cement particle board (DSP) can be very useful in construction and repair, being used quite often for finishing and flooring frame structures. Such material is a leader in many respects on the modern market.
It will be a very advantageous option when used in conventional living rooms and public areas, but especially where the humidity level is constantly higher than normal: in bathrooms, showers, kitchens, swimming pools.
Such slabs can also be irreplaceable when arranging facades and paved paths; as a thermal and sound insulator; for the construction of window sills, canopies and other similar structures.
DSP board– a multicomponent material produced in a factory by pressing and subsequent fermentation. The components used in the composition are a mixture various materials:
- Portland cement is the main one, containing about 65% of the total volume;
- wood shavings are the second most important component (24%);
- during production various minerals, as binders;
- other chemical ingredients and water.
This composite material ultimately takes the form of sheets of different sizes, corresponding to state standards. Positive properties the resulting building element, which has been relevant for a number of decades, has quite a lot. Let's list the most important of them.
1. Multifunctionality. The use of slabs is multifaceted: they are perfect for decorating rooms for various purposes; there are special slabs for flooring; DSP is widely used for the construction of internal partitions of rooms.
2. Environmental friendliness. The boards contain only safe substances. The release of harmful vapors and elements into the atmosphere during production is completely eliminated.
3. Big choice material parameters. Dimensions of the CBPB board are widely represented in the assortment. Modules of 3200x1250 mm are considered standard. But significant deviations are allowed depending on the thickness of the sheets, which can be from 8 mm and much higher. If the last parameter is large, it is also possible to change the length and width upward.
4. All products have a quality passport, certificates and comply with GOST. Therefore, purchasing products from major manufacturer, there is no doubt about its quality.
6. Durability. With external similarity to wooden structures, the material is more reliable. Therefore, most often, it is preferable to wood. This indicator is ensured by a three-layer structure. The outer layers, located on both sides, consist of small chips. The internal contents contain stronger formations.
Here you should also add the smoothness of the material, its resistance to moisture, ease of installation and affordable prices, possibility of operation in difficult conditions. A separate disadvantage can be considered the short service life in a particularly aggressive environment. But it is also about one and a half decades. However, by creating additional protection, it is possible to significantly extend quality life material.
Kinds
There are three types of DSP. Studies of the material have accurately shown that each of them does not lose its valuable properties even during multiple cycles of significant temperature increases and subsequent defrosting.
Resistance to fire and particularly humid environments, negative biological factors. But each type of slab has its own characteristics, which include the production method, the difference in source materials, the characteristics of the finished product and the scope of application. Among the types you can indicate.
1. Fiberboard. Its basis is the so-called wood wool, which is long-fiber shavings. The composition also includes inorganic binders.
Wood strips produced on special machines are impregnated with solutions of calcium chloride and liquid glass. The raw materials are pressed into molds and subsequently dried. The thickness of such slabs can reach 150 mm, but there are a number of much thinner parameters.
These building elements, with their considerable strength, are excellent for thermal insulation. A similar material is also used as an acoustic material.
It is easy to process and soft, for this reason it is in demand for multifaceted repairs, as well as reconstruction work of various structures. During construction operations with slabs, due to their low weight, lifting equipment is not required, and therefore their use is very economical.
2. Wood concrete. It is classified as lightweight concrete and contains small shavings, sawdust, reed chaff or rice straw. The highest quality slabs of this variety are made from wood chips.
If the basis of the composition is wood shavings, then the material is usually called wood concrete, if sawdust - sawdust concrete. The two types mentioned have slightly reduced performance characteristics compared to the first one mentioned above.
They are heavier, denser and subject to unpleasant deformations, but they are also somewhat cheaper. The scope of application of wood concrete is quite wide. But mainly it is in demand as a material for low-rise private construction, especially popular in the manufacture of wall partitions, also for finishing and thermal insulation.
3. Xylolite is most often known in application as a coating. DSP for flooring. Plates, similar to those previously described, are made from wood waste, differing from other types in production technology. On sale, the presented assortment pleases with a variety of colors.
The material is distinguished by excellent thermal insulation qualities and increased strength. It does not burn in an open fire, but only gradually chars; even when boiling, it does not get wet in water and is only slightly thermally conductive; It has enviable elasticity and is hard like stone, but at the same time it is easily processed like wood: drilled, planed and sawed. In addition to the above, it is ideal for use as cladding for stone, covering stairs, window sills, and roofs.
An important characteristic is weight of the CBPB board. Such indicators are simply necessary to know during construction and other work. The specified data is very useful in transporting cargo and at the time installation work. The mass of one module directly depends on the thickness and, knowing this indicator, it is easy to calculate. After all, for every 10 mm there is approximately 54 kg of tile weight.
Application
Using slabs to cover the floor is extremely convenient. To acquire an aesthetic appearance, there is no need for subsequent finishing. Their surface is easily treated with paint of a special composition.
It is also possible to use water-repellent dyes or regular ones. Such panels look advantageous against the backdrop of any interior, without disturbing the aesthetics, satisfying even the most picky and demanding taste.
Of course, excellent quality installed slabs there is a chance to enjoy only after best installation carried out according to all the rules. If the modules are carelessly secured and poorly processed, this will significantly reduce not only appearance general design, but also service life DSP.
But use of slabs in the process of finishing the walls and floors of various rooms in the correct way, results in practical use great result. In addition, if necessary, it provides almost perfect thermal insulation and a very durable coating.
Laying on the floor is done by screwing it to the sheathing using self-tapping screws with a countersunk head. During installation, everything depends on the material of the array. If it is steel, then the screws are screwed in by 10 mm, but if it is wood, they should go into the base of the beam by 20 mm.
It should be remembered that despite its remarkable properties, the basis of the material is wood. This means that the slabs, albeit slightly, have the ability to expand under the influence of moisture. Therefore, when finishing with DSP boards the presence of an expansion joint is often necessary. This is mandatory:
- next to walls, thresholds, columns and others vertical structures;
- if you plan to change the type and thickness of the floor;
- in case of a large coverage area.
These slabs play an important role in creating formwork. Moreover, in this and other cases, the choice of this particular material will entail many advantages: it will help to build a reliable structure, in a short time and with absolutely minimal costs.
In this case, additional cladding will not be required here, since the structure will already have a completely finished, certainly attractive appearance and high-quality characteristics. For the reasons listed above, such slabs are in great demand.
And when choosing the required thickness of the modules, it is better to obtain preliminary special consultation. It can be clarified that when finishing the floor, the optimal indicator ranges around 30 mm.
It is recommended to use special DSP slabs for facade. This material in this quality looks extremely advantageous in appearance. For best protection It is better to choose external coating modules of the maximum possible thickness.
This will protect general design structures, as well as the foundation, from negative external factors: strong winds, heavy rains, etc. Advantage of application DSP facade slabs is the possibility of further painting in any desired color, while the surface will appear as smooth as possible, which is very suitable for varied and original design solutions.
At the same time, the combination of contrasting colors looks extremely advantageous. color ranges so that the walls and roof of the house are different colors which will provide wonderful results.
They look especially attractive, even stylish, when used for finishing and creating an additional barrier of protection between the internal elements of the building and the external sphere DSP boards for brick or stone.
They differ from other types in their composition, built exclusively from the smallest particles of raw materials. Such sheets are in undoubted consumer demand.
Their convenience is that there is no need for subsequent processing with paints and other special compounds. That is, immediately after release they are ready for installation, and therefore are considered a popular finishing material.
Price
The low cost of the material does not affect its quality characteristics, which is ideally capable of solving many construction problems. Moreover, tile production technology is regularly improved and tries to adapt to complex and sophisticated consumer needs.
For example, the range has recently been updated with ultra-thin slabs, the thickness of which reaches 4 mm. The advantage of this type of product is that there is no need to use grinding machines to process such slabs, which undoubtedly affects the cost of the product offered.
A brand that has become especially famous lately is Tamak. The company produces finishing materials, causing great interest in the market. CSP boards are available in a variety of sheet sizes with thicknesses starting from 8 mm.
When choosing similar material individual characteristics should be the object of close attention. Among important indicators: size parameters, properties, composition. At normal humidity, according to existing standards:
- the slab should swell by less than 2% of the total volume of the material;
- the ability to absorb water cannot exceed 16%;
- density should not be more than 1300 kg/m2;
- The roughness of the panel for plates processed by grinding must be 80 microns.
Retail prices of CBPB boards are invariably dependent on leaf sizes. average cost material:
- with a thickness of 10 mm it averages about 950 rubles;
- if the thickness is doubled – 1,700 rubles;
- three times - from 2000 rudders and above.
When purchasing material, it should be borne in mind that prices for wholesale buyers are undoubtedly significantly reduced.
When planning to build a large private house several floors high, it is better to choose the thickest possible slabs when purchasing in order to subsequently achieve stability and strength in the structure.
Of course, such sheets will cost much more. As a rule, slabs that go on sale come in the most simple colors, intended for further coloring, according to the choice of the desired shade.
But from an aesthetic point of view, it is better to choose samples with decorative coating, paint adheres better to them, and color options are purely individual and have no repetitions.
Slab products modern market provides enough. However, DSP boards are recommended by experts as among the best, having wide application at any stage of construction. At the same time, only rare ones can compete with them in quality Construction Materials.
